TRANSMITTER-SUPPORT.

Specification of Letters L Patent.

Patented June 19, 1906.

Application filed February 28, 1905. Serial No. 247.683-

' To all whom it may concern.-

Be it known that I, SIDNEY A. BEYLAND, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and. useful Improvements in Transmitter Supports, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to arms, mountings, and supports for telephone-transmitters, and especia y to such as are required to be compact and of limitedcompass, though having perfect adjustability within the space limits permitted.

In so-called "hotel sets and the like the transmitter must be carried with a very short arm upon the front of the casing or box, and yet must have a certain range of movement to adapt it to persons of different heights. In such cases the instrument need have no side motion, but can be turned up or down in a vertical arc. While I do not limit my design to one direction of adjustment, I have confined the illustration and shall confine this description thereto for the sake of conciseness and clearness.

In designing this support I have been guided by the eneral rule of economy in labor and materia but have not thereby sacrificed efficiencg but, on the contrary, have found it possi le to secure a su erior pivot joint which gives any required adjustment and is also very economical to manufacture and easIy to assemble.

n eneral, I ma state the invention as embo 'ed in a bafi-and-socket joint with spring take-up and a single securing-bolt, the socket being formed in a sheet-metal plate which may or may not be a part of the front of the containin -box of the telephone-set, and the ball ein either a solid casting adapted to be secure to the shell of a transmitter of any make or also formed up out of the sheet-metal shell itself. The socket is slotted or pierced with an opening of sufficient size to give play to the securing-bolt, and the latter carries a spring pressing on the inside of the socket-plate, and, if desired, provided with fingers extending through socket and ball to act as guides or limiting stops to the motion.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a side view, partly in section, of a wall box and transmitter employing my improved joint. Fig. 2 is a sectional view of the joint applied to the front of a wooden box. Fig. 3 is a front view of the socket shown in Fig. 2. Fig. 4 is a section of the same with a solid ball-base for the transmitter. Fig. 5 is a rear view of the same. Fig. 6 is a vertical section similar to Fi 2 showing a modification. Fig. 7 is a orizontal section of the same modification.

The construction shown in Figs. 1 to 5, in

elusive, is identical as regards the essential points of my invention, Fig. -1 being, however, confined to the showing of a telephonewall box formed out of sheet metal, while the other figures show the plate containing the socket as separatel made so as to be ap licable to any telep lone. It will be undbrstood, therefore, that the first part of this descri )tion relates to all these figures. In these P is the ball 'or protuberance, really formed in hemispherical shape to fit the socket S. Where the entire instrument is made and assembled once for all, this ball is preferably simply a projection of the rear portion of the shell of the transmitter T, as shown in Fig. 1. In other cases, however, it

may be either a hollow or a solid stub, as

shown in Fig. 4, to which any standard transmitter-shell may be attached. The socket S is formed in a metal plate C, which in Fig. 1 is the front of the box, and in the other figures is separate, as already pointed out. Thisplate, if separate, is provided with ears for attachment to a box or back board, perforated for the passage of bolts S, whose heads overlie washers on the inside or back of the board and their stems engage cap-nuts R, shouldered to overlie the edges of the holes on the outside and forming a finish therewith. The cap-nuts only need be nickeled .01 burnished, and yet this mode of fastening will give a very pleasing appearance, while the solidity of the fastening is absolute. The socket has its convex wall slotted, as shown at x, and pierced with openings H H for the passage of the transmitter-cord conductors. On the inside face of the convexity lies a spring A, having guide-fingers B and frictionfingers F, the general shape of the spring being spider and its central point being pierced for the bolt K, which secures the ball in the socket. The head of this bolt lies in the inside or cup ofthesgcket, and its shank extends out through the rear wall, lying in the slot w and ca ing on its end the set and lock nuts N etween these nuts and the convex surface of the socket lies the spring A, whose fingers B are turned in to pass through the slot above and below the olt and with their ends lying in openings in the ball or stub of the transmitter. The fingers F, on the other hand, extend out over the surface of the socket-wall and press more or less thereon as the bolt K is turned up more or less in adjustment after assembling. Suflicient friction is thus assured to hold the transmitter at an angle to which it may be set in use, While t e fin ers B serve as guides to make 'the only possi le motion a vertical one, as they must move in the slot m.

In Figs. 6 and 7 I have shown a substitute for the guide-fingers B, the friction-fingers F only bein employed. Here the wall of the socket an the registering wall of the ball are provided with a feather or ridge cut or formed in the metal, so as to prevent any side motion as the transmitter is turned on the joint. Other substitutes will occur to those familiar with this class of devices and their manufacture, all of which I shall include in the scope of my claims, although I do not consider it necessary specifically to describe them. These and other changes in my design which do not depart from the spirit of my invention are all to be read in as if I had specifically set them forth. The main feature of the invention is the production of a perfect and smooth-working joint without the usual millin out or grinding or machining of any sort, t us saving great expense in the a gregate, making the joint, moreover, self-adjusting, so as to take up wear and having the design universal in its application. Obviously the parts might be reversed-that is, the socket put in the transmitter-shell and the projection on the base-without sacrificing this feature.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is I 1. In a transmitter-support, a base-plate and a transmitter-mounting provided with curved surfaces nesting together to form a ball-and-socket joint, and means passing through both and securing said parts to gether, one of said parts provided with an opening to permit play of said securing means.

2. In a transmitter-support, a sheet-metal base formed up with a curved socket of spherical figure, a transmitter mount or shell havin a curved projection tofit the socket, a be t for securing the arts together, and a friction-spring secure by the bolt to one part and moving on the other, together with an opening in the latter permitting play of the bolt.

3. In a transmitter-support a metal baselate, a curved socket formed therein, a simiarly-curved transmitter-mount fitting the socket, a vertical slot in the socket-wall, a bolt secured in the mount and passing through said slot, a nut on said bolt, a friction-spring held by said nut against the inner surface of the socket -plate, and projections on said spring extending through said slot into engagement with said mount to serve as limiting-stops for the motion thereof.

4. In a transmitter support, the sheetmetal plate C having the curved socket S, a transmitter mount or shell having the cooperating curved projection P, a slot so formed in said socket, a bolt K attached to the part P and playing in said slot, a spring A held by said bolt against the inner face of the socketplate, friction-fingers F on said spring, and stop-fingers B extending through the slot into engagement with the curvedprojection P.

5. In a transmitter-support, the base and transmitter-mount provided with cooperating curved friction-surfaces, a single securing device and spring take-up therefor, and means to prevent side play.

6. In a transrmtter-support, a ball-andsocket joint, openings therein to pass circuitwires, and a single securing device passing through said ball-and-socket joint, substantially as described.

7. In' a transmitter-support, a base-plate having a curved socket, a transmitter-shell having a curved projection formed integral with its body, and resilient means to secure the shell upon the plate, substantially as described.

8. In a transmitter-support, a base-plate and a transmitter-mounting provided with curved surfaces nesting together to form a ball and socket, resilient means holding said parts in frictional relation and securing means therefor, one of said parts having an opening adapting to permit play of said adjusting and securing means.

In testimony whereof I affix my signature in presence of two witnesses.
